IMPROVEMENT IN MACHINES FOR WASHING PHOTOGRAPHS.

Sp eciication forming part of Letters Patent No. 141,658, dated August12, 1873; application filed February 10, 1873.

To all whom it may concern:

Be it known that I, LUTHER V. MoULToN, of Beaver Dam, in the county ofDodge and State of Wisconsin, have invented certain Improvements inMachines for Washing Photographs, of which the following is aspecification:

The iirst part of my invention relates to an improved combination of arevolving cylinder with stationary pipes in such a manner that water maybe applied to both sides of the prints, thereby'thoroughly removing thelixing agent in a very short time. The second part of my inventionrelates to an improvement in the construction of the above-mentionedcylinder, wherebythe machine is made more convenient to operate, and ofgreater capacity.

Figure l is an elevation, showing that end of the machine which is atthe right hand in Fig. 2. Fig. 2 is a vertical section,.showing theparts of the machine which are at the right hand of the line .fr x inFig. 1. Fig. 3 is a section of the cylinder on the line y, showing theposition of the bars e e e c. Fig. 4 is a portion of the surface of thecylinder, showing the construction of the netting f.

Like letters refer to like parts in all the iigures.

The case a'serves to collect the water, and is supported by the frame b.c is the cylinder, constructed as hereinafter described, and supportedon the right by the crank shaft g and on the left by the pipe h, uponwhich it revolves, and which is perforated with a row of small holes toallow the water to escape. i is another pipe similar to 71., placed inthe top of the case a to operate upon the outside surface of the printsto be Washed.

The cylinder c is constructed of two wheels, c c, having teeth d to holdthe netting and openings o o o o through which to put the prints in andremove them from the machine, and connected by bars c e c e, placed at adistance from the periphery to admit of placing the prints under them onthe netting `]",which is made of small twine or other suitable materialattached to the teeth d, as shown in Fig. 4, to carry the prints andallow the Water to act upon them as it is forced under the netting f bythe motion of the cylinder, and which is also made continuous throughoutthe entire circumference of the cylinder to obtain the greatest possibleamount of surface.

The photographs to be washed are taken while wet and placed on theinside ofthe netting, to which they will adhere. A rotary motion beingimparted to the cylinder c, and water turned on, any solution remainingin the prints is quickly removed by the water escaping from the holes inthe pipes It i.

I am aware that the combination of a cylinder with a'central pipe andcase has been used for the purpose of washing photographs; but, so faras I am aware, it has proved ineffectual, because photographic paper isimpervious to water, and the pipe h, throwing water on only one side ofthe paper, would not remove the fixing agent from the other side, incotiiseoluence of which the prints would soon I claim as myinvention- 1. The combination of the pipe i with the cylinder c and casea, substantially as and for the purpose specified.

2. The combination of the wheels c c with the bars c c c e and nettingj', substantially as and for the purpose specitied.
